Ambient Occlusion

Ambient Occlusion.

The Ambient Occlusion shader computes how much the hemisphere above the shading point is occluded. This can be used for procedural texturing, for example to add weathering effects to corners only.

For Cycles, this is an expensive shader and can slow down render significantly. If render time is a concern, using Pointiness from the Geometry node or baking Ambient Occlusion will render faster.

Entradas

Color

Tint for AO output color.

Distance Cycles Only

Distance up to which other objects are considered to occlude the shading point.

Normal

Normal used for ambient occlusion; if nothing is connected the default shading normal is used.

Properties

Samples Cycles Only

Number of samples to use for ray-traced ambient occlusion sampling. Keep as low as possible for optimal performance.

Inside Cycles Only

Detect convex rather than concave shapes, by computing occlusion inside mesh.

Only Local Cycles Only

Only detect occlusion from the object itself, and not others.

Salidas

Color

Ambient occlusion with color tint.

AO

Ambient occlusion factor without color tint.
